Persistent Leg Numbness and Pain After Lumbar Injury: What to Do?

Numbness and pain in the legs after a spinal injury?

About three months ago, I accidentally bumped the right side of my lumbar spine while changing positions in a chair.
Shortly after, I began to experience numbness and pain in my right leg.
A week later, I visited a rehabilitation clinic with an X-ray machine and was informed that there were no issues with the bones, but I had a 7.4-degree scoliosis.
The doctor explained that the bump might have slightly irritated a nerve and arranged for rehabilitation.
However, after one session, I found that it increased the numbness in my right leg, so I did not return.
The problem persists to this day; sometimes the numbness and pain extend from the front or back of my thigh down through my entire leg, and at other times, it affects specific areas (such as the front of my thigh, front of my calf, or the top of my foot).
This occurs intermittently whether I am lying down, sitting, or standing, and the frequency and intensity of the numbness and pain have remained unchanged.
Should I seek medical attention again, or is it possible that it will resolve on its own?

It may be sciatica, and further evaluation at the hospital is necessary.

Persistent leg numbness and pain following a lumbar injury can be concerning and warrants careful consideration. Given your history of a lumbar injury and the subsequent symptoms of numbness and pain radiating down your right leg, it is essential to approach this situation with a comprehensive understanding of potential underlying issues.

Firstly, the fact that you experienced numbness and pain shortly after the injury suggests that there may be some involvement of the nerves in the lumbar region. The lumbar spine houses several nerve roots that can be affected by trauma, leading to symptoms such as numbness, tingling, and pain that radiates down the leg. This is often referred to as radiculopathy, which occurs when a nerve root is compressed or irritated.

The X-ray findings indicating a 7.4-degree scoliosis may also play a role in your symptoms. Scoliosis can alter the biomechanics of the spine and potentially lead to nerve compression or irritation. Additionally, if there was any soft tissue injury, such as a muscle strain or ligament sprain, it could contribute to your ongoing discomfort.

Since your symptoms have persisted for three months and have not improved, it is advisable to seek further medical evaluation. While some minor injuries may resolve on their own, the duration and nature of your symptoms suggest that a more thorough investigation is warranted. Here are some steps you might consider:
1. Consult a Specialist: It would be beneficial to see a spine specialist, such as an orthopedic surgeon or a neurosurgeon, who can provide a more detailed assessment of your condition. They may recommend advanced imaging studies, such as an MRI, to evaluate the soft tissues, discs, and nerve roots in your lumbar spine.

2. Physical Therapy: If you have not already done so, consider engaging in a structured physical therapy program. A physical therapist can develop a tailored exercise regimen to strengthen the muscles supporting your spine, improve flexibility, and potentially alleviate nerve compression. It is crucial to communicate any worsening of symptoms during therapy, as modifications may be necessary.

3. Pain Management: Discuss pain management options with your healthcare provider. This may include medications such as non-steroidal anti-inflammatory drugs (NSAIDs) or muscle relaxants to help manage your symptoms. In some cases, corticosteroid injections may be considered to reduce inflammation around the affected nerves.

4. Monitor Symptoms: Keep a detailed record of your symptoms, including when they occur, their intensity, and any activities that exacerbate or relieve them. This information can be valuable for your healthcare provider in determining the best course of action.

5. Avoid Aggravating Activities: Until you have a clearer understanding of your condition, it may be wise to avoid activities that exacerbate your symptoms, such as heavy lifting or prolonged sitting.

In summary, while some minor injuries may resolve spontaneously, the persistence of your symptoms suggests that further evaluation and intervention are necessary. Seeking a specialist's opinion and engaging in a comprehensive rehabilitation program can help address your symptoms and improve your quality of life. Remember, early intervention can often lead to better outcomes, so do not hesitate to seek medical advice.
